CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of PCT/CN2012/073107filed on Mar. 27, 2012, which claims the benefit of Chinese PatentApplication No. 201110107439.0 filed on Apr. 28, 2011; the contents ofwhich are hereby incorporated by reference.

BACKGROUND

1. Technical Field

The present application relates to a container capable of convenientlymeasuring volumes of various liquid fluids, and more particularly to acontainer capable of pouring out a liquid in a fixed quantity orcontinuously pouring out the liquid.

2. Related Arts

With the continuous improvement of the production and living standards,people use more and more liquid articles every day, so people urgentlyneed a measuring tool for conveniently measuring volumes and weights ofthe articles. For example, when cooking dishes (especially preparingdishes according to a cookbook), weights of ingredients such as oil andvinegar need to be measured accurately. It is not very accurate to meterand judge the ingredients with naked eye by experience, and thedeliciousness of the food is affected to a certain extent. Especiallyfor people unfamiliar with cooking, it is more difficult to judge thequantities of seasonings.

Due to lack of a liquid metering container and package which areconvenient to use, have high compatibility and are safe and inexpensive,people mostly perform estimation by experience, thereby bringing muchinconvenience to the production and life.

SUMMARY Technical problems

In view of the problem in the prior art, the present application isdirected to a container capable of pouring out a liquid in a fixedquantity. The container not only can accurately meter and take a liquidfluid but also can directly pour out a non-metered liquid, so as toachieve compatibility between fixed-quantity taking andindefinite-quantity taking of the container in a simple manner. Anexternal quantifying cup is disposed, so that a user can clearly see aquantity of a liquid in the quantifying cup, and it is convenient forthe user to perform an operation on the liquid in the quantifying cupfor a second time (for example, pour out only half of the liquid). Theexternal quantifying cup can also collect a residual liquid at an outeredge of the fluid guide port. It is easy to process and form thisstructure all at once, thereby reducing the manufacturing cost.

Preferably, a fluid discharge port of the quantifying cup is disposed onthe external quantifying cup, and the fluid discharge port of thequantifying cup is located at the upper opening of the quantifyingdevice.

Preferably, a certain inclined angle exists between the fluid dischargeport of the external quantifying cup and the fluid guide port, so thatwhen the container is tilted towards the fluid discharge port of theexternal quantifying cup, the liquid in the quantifying cup can bepreferentially poured out through the fluid guide port and the fluiddischarge port of the external quantifying cup, so it is convenient forthe user to take the liquid in a fixed quantity.

Preferably, a bottom or a side wall of the external quantifying cup isconnected to the quantifying device in a movable manner, such that thevolume of the quantifying cup is changeable.

Preferably, a movable slide block is disposed on the injection port, anda height of the injection port is defined by pushing and pulling theslide block, such that the volume of the quantifying cup is changeable.

Preferably, a sealer is disposed on the fluid guide port, and the sealeris an easy-to-open seal or a sealing sheet, so as to hermeticallypackage the liquid in cooperation with the container conveniently.

Preferably, a cross section of the external quantifying cup is atriangle or a trapezoid.

During use, first, the container is tilted to inject a liquid into thequantifying cup when the upper sealing cover is closed, and then, thecontainer is placed upright, and the upper sealing cover is opened, andthe container is slightly tilted, so the liquid in a fixed quantity inthe quantifying cup is poured out. The tilt angle may also be changed tocontinuously pour out the liquid directly through the fluid guide port.

The upper sealing cover and the quantifying device may be disposed as anintegrated structure or a separated structure.

A container capable of pouring out a liquid in a fixed quantity includesa quantifying device, an upper sealing cover and a container body, inwhich the quantifying device includes a connection cavity running fromtop to bottom and an external quantifying cup capable of measuring aliquid, a fluid guide port is disposed on an upper portion of theconnection cavity, a lower portion of the connection cavity is fixed tothe container body, the external quantifying cup is located outside thecontainer body and the connection cavity, the external quantifying cupintegrally extends from the outside of the connection cavity to one sideof the connection cavity, so that the external quantifying cup raisesfrom one side of the connection cavity, an opening portion is disposedon an upper portion of the external quantifying cup, the upper sealingcover corresponds to the opening portion and the fluid guide port, sothat when the container body is tilted and the upper sealing cover sealsthe opening portion, the liquid in the container body is capable offlowing into the external quantifying cup through the connection cavitywithout flowing out of the container, and when the upper sealing coveris opened, the liquid in the container body is capable of flowing out ofthe container through the fluid guide port or the liquid in the externalquantifying cup is capable of flowing out of the container through theopening portion, and a height of a lowest place of the fluid guide portis not higher than a height of the opening portion of the externalquantifying cup.

When the upper sealing cover is closed, the upper sealing cover tightlypresses against the opening portion of the external quantifying cup, theupper sealing cover is equivalent to another “side wall” of the externalquantifying cup, and meanwhile, a gap exists between the upper sealingcover and the fluid guide port. In this case, the container bodycommunicates with the external quantifying cup, and the liquid in thecontainer body is capable of flowing into a “measuring cup” formed bythe external quantifying cup and the upper sealing cover forpre-measurement. When the upper sealing cover is opened, the liquid inthe external quantifying cup can be discharged via the opening portionthrough tilting and rotation at different angles, so as to realizetaking in a fixed quantity; and the liquid in the external quantifyingcup may also be discharged directly through the fluid guide port of theconnection cavity, so as to realize taking in an indefinite quantity.

The fluid guide port is surrounded by an annular cylindrical wall. A topend surface of the cylindrical wall is recessed downwards to form aninjection port. The injection port communicates with the externalquantifying cup. The cylindrical wall is located in an upper portion ofthe connection cavity. A height of a lowest place of the injection portis not higher than a height of the opening portion of the quantifyingcup, that is, a height of a bottom side of the injection port may beequal to or lower than the height of the opening portion.

When a liquid is taken in an indefinitequantity, the liquid in the container body may be directly poured outthrough the fluid guide port.

A long diameter of the opening portion of the external quantifying cupis not less than a depth of the external quantifying cup. Duringpre-measurement, the upper sealing cover is closed, the container istilted, and the liquid flowing out of the fluid guide port flows intothe “measuring cup” jointly formed by the external quantifying cup andthe upper sealing cover. When the liquid is poured out, the uppersealing cover is opened, and the external quantifying cup has a largeliquid discharging diameter, so it is only necessary to tilt thecontainer at a small angle to discharge the liquid in the externalquantifying cup, which is convenient for operations. The long diameterrefers to a maximum diameter of the opening portion.

A cup wall inversely inclined towards the opening portion is disposed atone side of the external quantifying cup far away from the connectioncavity, so that when the container body is tilted towards a fluiddischarge port of the external quantifying cup, the liquid in thequantifying cup can be preferentially poured out through the fluid guideport and the opening portion, so it is convenient for the user to takethe liquid in a fixed quantity. Therefore, the external quantifying cupmay be of a shape with a big upper part and a small lower part.

The injection port is disposed on the cylindrical wall.

An easy-to-tear sealer or a disposable sealer is disposed on the fluidguide port.

The external quantifying cup has a side wall and a bottom, and at leastone of the side wall and the bottom is movable, so that the volume ofthe external quantifying cup is adjustable.

A movable slide block is disposed in the injection port. A depth of theinjection port is defined by pushing or pulling the slide block. Whenthe slide block is moved, the depth of the injection port is changed, soas to change the volume of the external quantifying cup.

The connection cavity, the external quantifying cup and the uppersealing cover are integrally formed.

DETAILED DESCRIPTION OF THE APPLICATION Embodiment 1

As shown in FIG. 1 to FIG. 4, a container capable of pouring out aliquid in a fixed quantity includes a quantifying device 1, an uppersealing cover 2 and a container body 3. The quantifying device 1 has twoinjection ports 8, for dividing a fluid guide port 6 into two parts. Ahorizontal location of a highest place of the fluid guide port 6 isdisposed at a place higher than a horizontal location of an openingportion 4 of a quantifying cup, so as to pour out a liquid in thecontainer body 3 in an indefinite quantity. A height of a lowest placeof the injection port 8 (a bottom side of the injection port) is equalto or lower than a height of the opening portion 4 of the quantifyingcup, so it is convenient for the liquid exceeding the bottom side of theinjection port 8 to flow back to the container body 3 when the containeris placed upright.

As shown in FIG. 11, during fixed-quantity use, first, the upper sealingcover 2 (the upper sealing cover 2 seals the opening portion 4) may beclosed and the container body 3 is tilted, so that a liquid in a fixedquantity is injected into the external quantifying cup 7, and then, thecontainer body 3 is placed upright and the upper sealing cover 2 isopened, and the container is slightly tilted, so that the liquid in afixed quantity in the external quantifying cup 7 can be poured outthrough a fluid discharge port 9 of the quantifying cup.

As shown in FIG. 12, during indefinite-quantity use, an angle may alsobe adjusted to continuously pour out the liquid in the containerdirectly through the fluid guide port 6.

An easy-to-tear sealer 11 is disposed at the fluid guide port 6. Here,the easy-to-tear sealer 11 is an easy-to-open seal. The upper sealingcover 2 and the quantifying device 1 may be of an integrated structure.

In this embodiment, the quantifying device 1 includes the externalquantifying cup 7 capable of measuring a liquid and a connection cavity16 running from top to bottom. The fluid guide port is disposed at anupper portion of the connection cavity 16, which means that the fluidguide port is an upper opening of the connection cavity 16. The upperportion of the connection cavity 16 has an annular end wall 19 and anannular cylindrical wall 18 extending upwards from the end wall 19, thatis, the fluid guide port 6 is surrounded by the annular cylindrical wall18. The injection ports 8 are disposed on the cylindrical wall 18. Thetwo injection ports may be symmetric with respect to an axis of theconnection cavity 16, one injection port close to the externalquantifying cup, and the other injection port far away from the externalquantifying cup. When the container is tilted, the liquid in theconnection cavity may flow into the external quantifying cup through thetwo injection ports.

In this embodiment, the external quantifying cup 7 integrally extendsoutwards from one side of the connection cavity 16, that is, theexternal quantifying cup 7 raises from one side of the connection cavity16.

In this embodiment, a cup wall 21 inversely inclined towards the openingportion is disposed at one side of the external quantifying cup 7 faraway from the connection cavity 16.

In this embodiment, a long diameter a of the opening portion 4 of theexternal quantifying cup is not less than a depth b of the externalquantifying cup 7. The long diameter refers to a maximum diameter of theopening portion 4. When the upper sealing cover is closed, the uppersealing cover is combined with the external quantifying cup 7 to jointlyform a “measuring cup”. The form of a long “measuring cup” is presentedin a direction perpendicular (or approximately perpendicular) to theconnection cavity 16. The upper sealing cover becomes a side wall of the“measuring cup”. That is to say, when the upper sealing cover is closed,the upper sealing cover is perpendicular to the connection cavity, or anangle exists between the upper sealing cover and the connection cavity,so that a right angle or an approximately right angle exists between the“measuring cup” formed by the upper sealing cover and the externalquantifying cup 7 and the connection cavity, so it is convenient for auser to take and observe a liquid during pre-measurement.

In this embodiment, the external quantifying cup may integrally extendoutwards from one side of the connection cavity, and the externalquantifying cup and the connection cavity may also be disposedseparately and connected together.

In this embodiment, during pre-measurement, a gap may exist between theupper sealing cover 2 and the fluid guide port 6. The upper sealingcover 2 may tightly press against the end wall 19 of the connectioncavity 16, and a gap exists between the upper sealing cover 2 and thecylindrical wall 18. Moreover, the upper sealing cover 2 may tightlypress against the opening portion 4 of the external quantifying cup.Edges of the opening portion 4 and the end wall 19 may form an upperopening of the container. During pre-measurement, the upper sealingcover 2 seals the upper opening.

Duringuse, first, an upper sealing cover 2 is closed and a container body 3 istilted, so that a liquid in a fixed quantity is injected into theexternal quantifying cup 7, and then, the container body 3 is placedupright and the upper sealing cover 2 is opened, and the container isslightly tilted, so the liquid in a fixed quantity in the externalquantifying cup 7 is poured out through a fluid discharge port 9 of thequantifying cup. A tilt angle may also be increased to continuously pourout the liquid in the container body directly from the fluid guide port6.

The upper sealing cover 2 and the quantifying device 1 may be of anintegrated structure. An easy-to-tear sealer 11 is also disposed on thefluid guide port 6. Here, the easy-to-tear sealer 11 is a sealing sheet.

In this embodiment, it looks like a part in the connection cavity 16 isdug to form the external quantifying cup 7.
